A civil police helicopter crashed in central Brazil on Tuesday afternoon, killing eight people including a suspect in the brutal murders of seven people, officials said on Wednesday. There were no survivors.

The accident happened on Tuesday afternoon when the helicopter crashed into a hill near Piranhas, a small town in the central state of Goiás. The civil police helicopter had participated in the reconstruction of an April 28 massacre at a farm in the town of Doverlândia.

The aircraft was carrying the pilot, his co-pilot, the suspect, four investigators, and an expert. "The helicopter crashed after flying for about 15 minutes and all eight people on board were killed, including the investigators and the suspect. We don't know yet what caused it," a police source said.

The suspect, 22-year-old Ali Souza Alves, was accused of beheading seven people at the farm in Doverlândia. He confessed to the brutal murders but gave conflicting statements about what took place. As a result, authorities decided to set up a reconstruction of the events on April 28.

Brazil's Security Ministry in Goiás said the helicopter was in a good mechanical condition and had undergone an inspection the previous day.
